I don’t read any YA. It’s mostly classic sci-fi, and some detective stories and occasional political thriller here and there. Maybe I just wasn’t paying attention, but the only time I recall past tense stories is when a character is describing something that happened off-scene. Narration is always present tense.

I can think of a handful of exceptions where the whole story itself is narrated from the perspective of someone telling a story, but those are notable exceptions for having a weird narrative gimmick (e.g. the excellent but dated Icehenge is written in the past tense because it consists of personal diary entries).
